(Answered) Calculate the moles of aqueous calcium carbonate present in

Academics

Calculate the moles of aqueous calcium carbonate present in a 50.00mL sample of a calcium carbonate standard solution, assuming the standard is known to have a hardness of 125 ppm (hardness due to CaCO3).

You can assume that the density of the sample is 1.000 g/mL and the molar mass of calcium carbonate is 100.0 g/mol.
